A Proof Of Concept of a simple desktop RSS reader with .Net Framework 3.5
You can get Sharp Develop (http://www.icsharpcode.net/opensource/sd/) 3.2 or 4.3 and build the solution, also you can use any Visual Studio 2008 or higher to build the solution.
The day that Google announced the inminent end of line of Google Reader I asked to myself "How much work could it take to create a RSS reader?" and this project is the answer to that question.
It is only a small Proof of Concept that is unfinished but it was done with 2 or 3 hours of coding and it can be the base for a greater implementation.
